Lo Wu Bridge is not only a narrow bridge at the time, only moving train, but no bridge unroofed shed, left to sun and rain. In 1959, the government will be the Lo Wu Bridge turned into steel and concrete bridge deck has also widened more than doubled. 1962, also stamped with an iron Peng Ding, added in the iron bridge on both sides of the iron railing, and covered the sidewalk. The 20th century, the early 70s, the author in Guangzhou Railway Administration to do secretarial work, on several occasions to the Footbridge is the first walk.

当时的罗湖桥不但桥面狭窄，只能行驶火车，而且桥身无顶无棚，任凭雨淋日晒。1959年，人民政府将罗湖桥改建成钢筋水泥桥，桥面也加宽了一倍多。1962年又加盖了铁皮篷顶，在铁桥两侧增设了铁栏杆，并铺上了人行道。20世纪70年代初，笔者在广州铁路局做秘书工作，曾多次到罗湖桥头漫步。

产品/Product：本公司主要生产灰口铸铁、球墨铸铁、蠕墨铸铁。

Al impurity, the floatabilities of hematite and aegirine were resemble, which is contributed to the existence of structrual iron ion on surfaces of both minerals. It is the structrual iron ion that accelerates the floatability of aegirine greatly and leads to difficult separation with hematite. 2. The basic mechanism of actions of fluorosilicate salts as selective depressants of aegirine during the direct flotation of hematite was investaged detaily by using FTIR and XPS spectrocppy, fluorosilicate salts are poor depressants for hematite, but are very strong depressants for iron-containing silicate such as aegrine in weakly acid medium, which can enlarge the flotation differences between two minerals.

运用X射线衍射、俄歇能谱等测试手段研究了赤铁矿与钠辉石纯矿物的晶体结构特征，表面破裂面的元素组成与赋存状态，发现在白云鄂博不同的矿床（氧化矿段，原生矿段，风化矿段）存在着三种颜色与可浮性均有所差别的钠辉石，其可浮性的差异主要是由于表面含铁量及Ca、Al等杂质含量的不同而引起的，结构Fe〓的存在导致钠辉石可浮性剧增从而与赤铁矿难以分离。

The main principle of the DCcontactor:The electromagnetism coil switches on electricity thetitle iron to match with the iron heart on,the suction of theelectromagnetism system overcomes the counterforce of the springarouses the action of the contact, the main electric circuitconnected;The electromagnetism coil cuts the power the counterforceof the spring arouses the title iron from move to open, the headcontact breaks to open the output electricity arc give or get anelectric shock in drive to arc-extinct-chamber and made longer,thestrong cooling dissociates and put out,the main electric circuitcuts off.

接触器的主要原理：电磁线圈通电，衔铁和铁心吸合，电磁系统的吸力克服弹簧的反作用力带动动触头与静触头接触，主电路接通；电磁线圈断电，弹簧的反作用力带动衔铁和动触头弹开，触头断开产生的电弧在灭弧室中受到磁吹灭弧和电动力驱动被拉长，并强烈冷却去游离而熄灭，主电路切断。

The reduction temperature has great influence in constituting slag and iron phase coacervation. High temperature will add iron phase carburize and fall down melting and accelerate iron phase coacervation.

Part II:The electrocatalytic oxidation of guanine, adenine, guanosine-5'-monophosphate and ssDNA was performed in the presence of iron bis(2,2':6',2"-terpyridine) and Fe tris(1,10-phenanthroline) complexes as a homogeneous catalysts with Fe redox couple. The electrocatalytic and electroanalytic properties of guanine with an iron bis(2,2':6',2"-terpyridine) complex was measured by the amperometry method using the rotating disk electrodes. Electropolymerization of iron tris(5-amino-1,10-phenanthroline) complex produced thin polymer films on a gold, platinum, nickel, and glassy carbon electrode.
